Application November 26, 1943, Serial No. 511,835

1 Claim.

This invention relates to a toy oil-pumping rig, and has for one of its objects the production of a toy which will simulate an oil-pumping rig in actual operation and appearance.

A further object of this invention is the production of a toy oil-pumping rig having a rotary water storage tank which is associated with a walking beam and an operating means to operate the walking beam and rotary water storage tank.

Other objects and advantages of the present invention will appear throughout the following specification and claim.

In the drawing:

Figure 1 is a side elevational view of the toy;

Figure 2 is a Vertical sectional view taken on line 2-2 of Figure 1;

Figure 3 is an enlarged central vertical sectional view through the rotary water tank and illustrating the supporting bearing therefor;

Figure 4 is a fragmentary side elevational View of the detachable walking beam operating rod.

By referring to the drawing, it will be seen that I designates the base or platform upon which the toy is mounted. The base I0 supports a toy oil well derrick II, and this derrick II carries a safety walk and railing I2 near the top thereof. A rotary tank I4 is journalled for horizontal rotation upon a bearing I5 carried by the base l0 and a driving pulley I6 is carried by the top of the tank I4, over which pulley I6 passes a driving belt I1. This belt I1 is driven from a pulley I1a carried by the drive shaft I8. The drive shaft I8 carries a suitable clutch I9 which may be operated to render the pulley II.a active, or to render the pulley free. A clutch-operating lever 2U is pivotally mounted on a bracket 2l to facilitate the operation of the clutch I9. The shaft I8 is preferably driven by a spring motor 22, such for instance as the type of motor shown in my previous Patent #1,608,783, issued November 30, 1926. Any preferred type of motor may be used for rotating the shaft I8, as this shaft may be operated by an electric motor or by hand without departing from the spirit of the invention. As

shown the spring motor 22 may be wound by a crank I8a which is carried by one end of the shaft I8, and this crank is mounted exteriorly of the removable housing 23 hereinafter described.

A walking beam 24 is pivotally mounted upon a removable standard 25, the lower end of. the standard 25 fitting in the supporting socket 26 carried by the base Il). The outer' end of the beam 24 carries a pump rod 21 which works freely in the pulley bearing 28 so that the beam 24 and rod 21 may be easily removed if desired, but

when assembled and operating these parts will give the appearance of a pump rod and walking beam structure. The bearing 28 extends vertically through the tank I4, and carries a suitable leak-proof packing 29 at the bottom of the tank and bearing. The pulley I6 may form a part of the tank I4, or it may be secured thereto in any desired manner. A discharge faucet 30 is carried by the tank I4 and may be opened while the walking beam 24 is in motion', to allow water to iiow out from the tank and into a suitable outlet 3l which may drain to a. suitable point of disposal,

The beam 24 is connected to an operating rod 33 at its rear end which rod is detachably secured to the crank 34 of the shaft I8 in a conventional manner, such as is illustrated in Figure 4. The beam 24 extends through a vertical slot 35 formed in the front portion of the housing 23 and the crank I3a also extends through a vertical slot 36 formed in the side of the housing 23. This arrangement will permit the removal of the housing 23 to expose the operating mechanism normally shielded thereby. The walking `beam 24 and standard 25 may also be removed thereby converting the toy into a rotary drilling rig with the power unit out in the open. This gives the appearance of a modern drill rig. A horizontal partition 31 is formed near the top of the housing 23, and is spaced below the roof 38 to provide a coin saving bank. One panel. 39 thereof is slotted to provide an opening through which coins may be inserted, and this panel 39 is preferably hinged, as illustrated, to permit the contents of the bank compartment 40 to be removed.

By carefuuy noting Figure 3 it will be seen that the rod 21 which is slidable in` the upper end of the bearing 28 will brace the bearing at its upper end and tend to prevent tilting movement under the pull'of the belt I1 upon the pulley I6. Furthermore, the upper end of the bearing will provide a guide for the rod 21 thereby avoiding an device may be made in a large size to provide a" novel lawn ornament. The size may be varied to suit the type of toy desired, and certain other l detail changes may be employed without departing from the spirit of the invention, so long asA these changes'fall Within the spirit of the appended claim.

Having described the invention, what I claim as new is:

A toy of the class described comprising a base,

a derrick carried thereby, a rotary tank simulatv ing a rotary pump, said tank having an outlet, a Vertical bearing supporting said tank for horizontal rotationha pulley, means fordriving said,

pulley, said bearing extending through the tank and pulley, a walking beam mounted adjacent
